Abstract

Using the critical
thermal maximum technique with heating at 18°C /hour and from very different temperatures acclimation, the
lethal temperature values and loss of equilibrium temperatures in eight pampasic species were identified. The
results show a physiological relationship with the various “ecological types” in relation to temperature. The
open-water fish and shore fish show greater tolerance than lower bottom fish, according to the stability of the
environment.
